Specification of Letters Patent.

Patented Aug. 2, 1921.

Application filed December 12, 1918. Serial No. 266,452.

To all whom it may concern:

Be it known that I, THOMAS G. DADE, a citizen of the United States, residing at South Fort Smith, in the county of Sebastian and State of Arkansas, have invented certain new and useful Improvements in Wheels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form'a part of this specification.

This invention relates to wheels and particularly to that class known as truck wheels.

One of the objects of the invention is to provide a wheel including a wooden tread or tire, the tire being so constructed that it may be easily attached to and detached from the wheel for inspection or repair.

In carrying out my invention, I prefer to construct a tire embodying the general characteristics of the tire described in my ap-' plications 141,309 and 257,90i, but according to .the present invention the tire may be constructed, ready to be applied and in condition to be shipped, to be substituted for a worn out tire, forming part of a previously used wheel.

I have also provided means whereby the webs, including the tire engaging flanges at the perimeter and the hubs may be standardized so that the same set of webs may be utilized in constructing wheels using tires of different Widths. For example for certain work, a wheel of a given diameter will requirea tire with an inch or a one and a half inch tread, while other wheels of the same diameter may require a tire with a two and a half inch tread.

' Ordinarily it has been the practice to keep on hand separate sets of patterns, one for each size of wheel, but according to my invention, one set of patterns may be employed to serve for all the wheels of a given diameter, even though the widths of the tires are variable. The variable requirements are taken care of generically by employing fillers or inserts of varying thicknesses to be disposed between the two halves orwebs of the wheel. These fillers are so constructed that they serve a multiplicity of advantages. Not only do they properly space the halves or webs of the wheel proper distances apart, but they are so constructed that they have interlocking engagement with respective halves to prevent any radial or side-wise movement of one half of the wheel wlth respect to the other.

Another important advantage is that the fillers act as packings, whereby the danger of the lubricant usually employed for the bear ngs of wheels, will be prevented from leaking around the periphery of the wheel, with its attendant disadvantages.

Other objects and advantages of the inventlon Wlll be specifically described hereinafter, 1t being understood that forms, operation and minor details of construction may beresorted to without departing from the spirit of the invention or sacrificing any of its advantages.

Fig. VI is a detail View of one of the wheel tire blocks.

In carrying out my invention, I prefer to construct a wheel of two side members 1 and 2, which I will hereinafter designate the disk members, because they have the general characteristics of a disk, provided with central, upwardly disposed hub flanges 3 and 4: respectively and peripheral radial inwardly inclined tire or rim embracing.

flanges 5 and 6, one for each disk. The in ner faces of the respective disks are provided with annular ribs 7 and 7, 8 and 8, adapted to interlock with the filler or spacing ring 9, between which and the inner side faces of the disks are provided lubricant distributing wicks 10 and 11, which supply lubricant to the bearings; the lubricant being adapted to be introduced into the grease space 12, through the filler 13. The disks and filler may be rigidly fastened together by a series of bolts 14, which are interchangeable with shorter or longer bolts, according to the variation in the distance that sar T to change the size of the hub sothat in actual practice, the patterns which are. used.

in the foundry for the manufacture of the two disks of the wheel have no hub projec tions but a particularhub section is attachedv to the pattern to make any length orsize of,

modified fforniofring, in which the two hub hub, this being accomplished by merely changing the hub section of the pattern.

I am aware that this is not a new practice and the application of such patternsissim; ply mentioned here as explanatory of what I consider a convenient way of carrying outcertain phases of my invention.

The tire or rimis adapted to be cone.

structed of a plurality of blocks so. cutand shaped that when assembled and. finished, they form a ring that may be applied .toa major portion of the wheel to form a tread therefor, and they may be treated prior totheir application to the, wheel form in .a manner specifically set forth in my appli: cation 141,309.

As described in the said .application,.the blocks are cut in segments and assembled end to end preferably with the fiber running lengthwise to the blocks and slightly undercut so that the major portion of the end pressure is exercised against the shortest fiber in the blocks.

periphery to form a ring. In addition to this, the blocks are scored or grooved seg-. mentally sothatcontmuous circular grooves 15 and 16 are providedin the sides. of the ring thus formed,',and into these grooves are received welded locking rings or bands17 and 18. These bands so firmly lock the segments together after they are put under pressure that a truly detachable wood .tire or rim is provided, which may be shipped to the customer for application to the wheel, which is an advantagev over the. present practice which requires that the wheel be shipped back to the factory each time that a new to be pushed away from those on the sides.

In other words, the filler will act as a sup- Then these blocks are. subjected to an even pressure about their.

port, bridging the space between the two halves 1 and 2. The filler also serves the purpose of acting as a packing to prevent relative movement of one of the disks with respect to the other, because annular ribs on'the respective disks become. embedded into the respective sides of the tiller when the two wheel members are drawn together by the bolts 14.

The ribs? and 7 and 8 and 8 alsopermit the halves to bedrawn-tight enough to.v .cause a firm .bindingof the flanges 5 andfi againstthewheel rimor tire. so that. any:

liability of thetire becoming loosewill be eliminated.

I may utilize metal and therefore doqnot.
